DEIO'U'NTABLE RIM FOR AUTOMOBILE-WHEELS.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed June 11, 1919. Serial No. 808,527,

To all whom it me: concern Be it known t at I, Jnnss l-I. WAG-BN5 nons'r, a citizen of the United States residing in the city of Jackson, county of Jackson, and State of Michigan, have invented certain new and useful Improvements in Demountshle Rims for Automobile-Wheels, of which the following is c specification.

This invention is a demountablc tire currying rim for automobile wheels to other with the fastening means for connecting the de-- mountable carrying rim to the fixed rim of the wheel body.

The obiect of the invention is to rovide an exceedingly simple, strong and curable form of fastening means which is capable of quick and easy manipulation and which will serve to accurately position the tire carrying rim upon the fixed rim of the wheel body. The invention also has for its object to provide certain novelties of construction where by the cost of manufacture is materially decreased and at the same time the connecting fetter/Euros of the device materially strength on With these and certain other objects in View, which will become apparent as the description proceeds, the invention consists m the novel sutures of construction, combination and arrangement, all of which will be more fully described hereinafter and pointed out in the appended claims.

In the drawings forming a. port of this specification, Figure 1 is a view of a tirev carrying rim having my novel form of clump connected thereto; Fig. 2 is a detail perspective view of nortion of a. bar from which a plurality o the clamps are made; Fig. 3 is a detail perspective view of; one of the clam s before being attached; Fig. 4 is a view o1 saidclamp taken from the opposite edge; Fig. 5 is side elevation of the clamp; Fig. 6 is a side elevation of :1. bar such as illustrated in Fig. 2 and showing the manner of cutting a. plurality of clamps and boring the same with one operation; Fig. I is a top plan view of the bar after the second operation has been erformed thereon showing the manner of hi renting a. plurality of clamps at one operation; Fig. 8 is an inverted plan view of a. ortion of the rim base, the inrolled bead laeing punched to receive the his toning lugs of the clamp; Fig. 9 is asectional PETSGEBCHVB showing the manner of connectmg 1; e clamp to the tire carrying run and an adjacent portion of the fixed through the solid inwardly or apertures rim to which the tire cnrr in Y rim is clamped; Fi 10 is a side elevn tioz i showing a portion or the tire carrying rim secured by bolt and nut to the fixed rim of the wheel body; F1g. 11 is a detail sectional view of n tlre currymg r m havi o a, solid inwardly pro ect ng bead instead 0 the inrolled head shown in Flgs. 1, 8 and 9; Fi 12 is a. sectiounl view of a straight side xedrim with the mrolled head, and clamp connected thereto; Fig. 13 is a detail sectional view of a fixed rlm having n. tire carrying rim mounted thereon, said tire carrying rim being )IO- vided with aquick detachable side rhig; *ig. 14 is a detail view of the fastening nut.

In carrying out my invention I employ a tire carrying rim A which may be of the clencher type such as shown in Figs. 1, 9 and 11 or it may be of the strei ht slde type as shown at A in Fig. 12 and A in Fig. 13, this straight side type also embodying en inwerdly depressed portion A adopted to receive the quick detachable tire engaging ring A." having the shoulder A which rides upon the outer ed of the rim and this ring is also provide with the foot piece A which is adopted to fit into the depressed portion of the rim. and provide a. proper seat for the head of the tire. To the tire carrying rim A, A, A or A there are attached any desired number of clamps B, these clumps being permanently connected to the tire carrying rim in the social manner hereinafter set forth. The 0 amps are preferably right angular in shape, one leg thereof being secured in en gement with the base of the rim while the other leg thereof projects inwardly and is apertured to receive the fastening bolt and the leg which is secured against the base of the rim is preferably bifurcated in order to produce two separated engagin members which are adapted to engage depressions formed in the fixed rim hereinafter referred to. In order to uickly and securely connect the clnmp'to the use of the rim I preferably rovide each clamp with the outwardly proecting lugs B which are adapted to be projected throu h the o enjngs C punched in the mrolled be C as own in Figs. 8 and 9 or glrlojectin bead C illustrated in Fig. 11 or t ough t e degassed portion A of the rim illustrated in 'g. 13. These outwardly roecting lugs 15' after bein passed thro r 0 openings are headed own or riveted as shown most clearly in Fig. 9 thereby rig idly and securely fastening the clamp. to the tire carr ing rim. The inwardly rojectmg ortion of the clamp is forms with the ob: hole B which is countei'bcred as shown at B and the other leg of the clamp is bifurcated as shown at B so as to provide spaced engaging members 13. In practice I prefer to construct the clamps from a bar or hot rolled section D shown in Fig. 2'and this bar is first operated upon to bore the holes, coun' tcrsink them and then cut the contour of the inwardly projecting portion oi the clamp. The bar is then turned over and the bifurcations B made therein and the clamps -cut apart and after the edges of the engaging members 13 are rounded off the clamp is ready to be attached to the tire carrying rim, the base of which has been previously punched to receive the outwardly z'ojccting' lugs 13 which as before stated are coded or riveted down thereby permanently and so curely connecting the clamp to the rim. The bolt opening it will be noticed is arranged between the cn uging members B and the outer face of this bolt opening is counterbored as shown to receive the tapered portion D of the nut D, this nut being screwed upon the threaded end D of the bolt D which is passed axially through the fixed rim E of the wheel body. This fixed rim E is of sheet metal and is channel shaped as shown having the inwardly projecting flange E upon the inner leg of said fixed rim, and the flange E upon the outer leg of said rim, the outer side of the rim base bei adapted to engage the flan c E while the mrolled head 0' or the soli bead C, or the depressed portion A of the rim is adapted to en egc the other flange E. The 1c of the nod rim are formed with a series 0 bolt openings It and E through which the bolts D= are adapted to be passed and upon each side of the bolt 0 ening E there are produced depressions into flanges E, these depressions being so spaced as to receive the members 13 of the clamps. By this arrangement a driving connection between the demountable rim and the fixed rim is secured and at the same time the bolt is arranged very close to the outer edge of the fixed rim thereby permitting the full binding force of the nut and bolt to be exerted upon the clamp. By havin g the bolt openings in the clamps counterborcd and the nuts providcd with tapering portions the parts willbecome properly centered or ositioned as the nuts are fastened upon the olts and by maintaining the clamps in their proper positions at all times, the proper coaction between the permanently attached lugs of the demountable tire carrying rim will properly functionwith the couliarly constructed fixed rim of the wheel ody so that the best results are obtained.

If desired the bolt D may be formed with a non-circular portion D' adjacent its head and which passes through a correspondingly slur )ed openin E in the leg of the fixed rim an at a suit-ails point a sto shoulder D may be provided after the oil; has been passed t rough the fixed rim. Then by pushing u )on the nut when the some is being unsorewc the bolt can be fed outwardly the desired distance to release the nut and clear the ends of the bolt from the clamp so that the dcmouutable rim can be tilted upon the fixed rim in order to remove the same.

It will thus be seen that I provide a novel construction of lug, and connect the sameto the deinountable tire carrging rim in a novel manner, and also that t is particular construction of clamp coacts'with the novel form of fixed rim and accomplishes the purpose of quickly, easily and securely "fastening the tire curr ing rim to the fixed rim of the wheel bo y. 7
